The Johto region is back. Heart Gold and Soul Silver are the newest remakes of the original Gold and Silver versions for the Nintendo DS. These games are the last of Generation IV, following Diamond, Pearl, and Platinum. The battle mechanics are the same, but the overworld takes a whole new spin. Pokémon now follow the player around outside of battle. The touch screen is used to its greatest potential so far, with touch screen menus and buttons. You have the ability to travel between Johto and Kanto allowing you to get 16 badges. A good deal of the plot goes back to the original Gold and Silver games, where you are trying to keep the evil Team Rocket organization out of trouble.
